HCL_ZeroBiLinearOp_d( HCL_VectorSpace_d * d1, HCL_VectorSpace_d * d2, HCL_VectorSpace_d * r )

Usual constructor; just needs pointers to the domains and range.

virtual HCL_VectorSpace_d& Domain1() const

Access to the domain of the first argument. Returns a reference to a HCL_VectorSpace_d.

virtual HCL_VectorSpace_d& Domain2() const

Access to the domain of the second argument. Returns a reference to a HCL_VectorSpace_d.

virtual HCL_VectorSpace_d& Range() const

Access to the range. Returns a reference to a HCL_VectorSpace_d.

virtual void Image( const HCL_Vector_d & x, const HCL_Vector_d & y, HCL_Vector_d & z ) const

Image computes the action of the operator on the pair (x,y), giving z.

virtual HCL_LinearOp_d* Op1( const HCL_Vector_d & x ) const

Access to Op1 as a linear operator.

virtual HCL_LinearOp_d* Op2( const HCL_Vector_d & y ) const

Access to Op2 as a linear operator.

virtual HCL_LinearOp_d* Op3( const HCL_Vector_d & z ) const

Access to the "partial adjoint" of the bilinear operator. Assume B:XxY --> Z is the bilinear operator. Then Op3 returns the operator x |---> (B(x))'z. Its adjoint is the operator y |---> (B(.)y)'z
